From 396d79c36cf91de3ecf0741c6157688a1600399b Mon Sep 17 00:00:00 2001 From: Eric Blake Date: Mon, 11 Jun 2018 16:39:27 -0500 Subject: [PATCH] iotests: Add test 221 to catch qemu-img map regression Although qemu-img creates aligned files (by rounding up), it must also gracefully handle files that are not sector-aligned. Test that the bug fixed in the previous patch does not recur. It's a bit annoying that we can see the (implicit) hole past the end of the file on to the next sector boundary, so if we ever reach the point where we report a byte-accurate size rather than our current behavior of always rounding up, this test will probably need a slight modification.
